包括周向增强元件的层的轮胎
摘要：
本发明涉及一种轮胎，所述轮胎包括胎冠帘布层，所述胎冠帘布层由增强元件的至少两个工作层形成，橡胶共混物的层C至少设置在至少两个工作层的端部之间，聚合物共混物的第二层S与至少一个工作层接触并且与胎体帘布层接触，并且胎冠帘布层包括至少一个周向增强元件的层。第一层C在10％伸长下的弹性拉伸模量小于8MPa，第一层C的用tan(δ)max表示的最大tan(δ)值小于0.100。第二层S由经填充的弹性体共混物制成，所述弹性体共混物具有大于或等于65的宏观分散系数Z和用tan(δ)max表示的小于0.100的最大tan(δ)值，并且所述第二层S在10％和60℃下在返回循环中测得的复数动态剪切模量G*大于1.35MPa。
摘要（英）：

The invention relates to a tyre comprising a crown ply formed by at least two working layers of reinforcing elements, a layer C of rubber blend being disposed between at least the ends of the at least two working layers, a second layer S of polymer blend being in contact with at least one working layer and in contact with the carcass ply, and the crown ply comprising at least one layer of circumferential reinforcing elements. The tensile modulus of elasticity at 10% elongation of the first layer C is less than 8 MPa, the maximum value of tan(delta), denoted tan(delta)max, of the first layer C being less than 0.100. The second layer S is formed by a loaded elastomer blend having a macro dispersion rating Z greater than or equal to 65 and a maximum value of tan(delta), denoted tan(delta)max, less than 0.100, and the complex dynamic shear modulus G* of said second layer S, measured at 10% and 60DEGC on the return cycle, is greater than 1.35 MPa.
